ELECTRODE FOR SOLDERING AN D DEPOSITING META LS BY THE ELEGTRIC ARC.

Specification of Letters Patent.

Patented June 1, 1920.

Application filed August 16, 1919. Serial No. 317,981.

' siding at Church street, Islington, London,

England, have invented new and useful Improvements in Electrodes forSoldering and Depositing Metals by the Electric Arc, of which thefollowing is a specification.

In the manufacture of electrodes for soldering and depositing metals bythe electric arc, the metal wire is wound with asbestos yarn, which inpractice occasionally becomes .loose and unwinds. This invention has forits object improvements whereby this defect is remedied.

According to this invention, a mechanical attachment of the yarn to thewire is effected at both ends of the electrode.

The accompanying drawings illustrate several examples of mechanicalattachment according to the invention. Figure 1 is an elevation and Fig.2 is a plan showing one end of an electrode wire a formed with a saw cut6 into which the end of the asbestos yarn c is forced and held.

Figs. 3 and 4 are similar views of one I end of an electrode wire aformed with a wedge shaped slot (1 into which the end of the asbestosyarn c is forced and held.

Figs. 5 and 6 are also similar views of one end of an electrode wire afitted with a ring or band clip 6 which is caused to grip the asbestosyarn a tightly to the wire a.

Fig. 7 is a modification of Figs. 5 and 6 in which the end of the wire ais tapered to receive a ring or band f of a diameter to grip the yarn atightly to the wire a when the ring or band f is forced on the end ofthe wire.

Fig. 8 is a modification of Figs. 1 and 2 the saw out or slot it beingformed at a suitable angle in the side of the wire a.

It will be understood that other mechanical methods of securing the yarnto the wire may be adopted. For. example, the slots 6, d and it may. bepartly or wholly closed after the yarn c has been inserted; an eye orother opening may be employed instead of the slot, and one or more turnsof wire or other material may be employed instead of the band clip e.

I claim 1. Electrodes for soldering and depositing metals by theelectric arc, comprising a metal wire, asbestos yarn wound upon saidwire, and mechanical fastenings for the ends of the asbestos yarn, asset forth.

2.. Electrodes for soldering and depositing metals by the electric arc,comprising a metal wire formed with a slot in each end, asbestos yarnwound upon said wire and having its ends secured in the slots of saidWire, as set forth.

In testimony whereof I have signed my name to this specification.

ERNEST HENRY J ONES.
